Spelling correction
As this is a spelling correction is in code (and outside my normal realm
of PRs) I created a separate PR for it. I cannot test it, b I'm quite
confident that it won't lead to problems. I think the old name contained
a typo.

The formula in Documentation/doc/biblio/cgal_manual.bib
```
@article{cgal:cgm-fobbo-11,
title={Fast Oriented Bounding Box Optimization on the Rotation Group $\SO(3, \mathrm{R})$},
author={Chang, Chia-Tche and Gorissen, Bastien and Melchior, Samuel},
```
renders incorrectly (see Optimal_bounding_box/citelist.html) as there is
no command `\SO` in LaTeX
The formula in doc/Kernel_d/CGAL/Kernel_d/Aff_transformation_d.h
```
\pre \f$ sin_num^2 + cos_num^2 = den^2\f$ and \f$ 0 \leq e_1 < e_2 < d\f$.
```
renders in an unexpected way (see
Kernel_d/classCGAL_1_1Aff__transformation__d.html) as the `_` is seen as
subscript operator in LaTeX
## Summary of Changes
Solve a bug for CMap and GMap when we iterate on an empty map with an
iterator that needs to mark cells, and when using index version.
